To Create a Predeployment Script

This script is run before the installation of the archive. If the script
is meant to validate the archive, it is kept in the archive. If the script
is meant to preserve local configurations on the clone system, it is kept
on the clone system. This script also can analyze and collect local data necessary
for later customization. For example, client-specific information can be saved
before being overwitten by files about to be extracted. This information can
then be used in the final stage after extraction.
